did you set the proper device as the target at

Projects/options/general options/ target in IAR project workspace.

Is this on a board you created, or a commercial eval board?

Check the wiring, and connection, of the JTAG port. Check if you want to use SWD vs JTAG signalling. Check you have current drivers and firmware from SEGGER.

this is the board created not a commercial eval board, I also have a commercial board on which it is working perfect.Check the wiring, and connection, of the JTAG port? Wiring and connection are proper.Check if you want to use SWD vs JTAG signalling. I wanted JTAG, but both are not working Check you have current drivers and firmware from SEGGER. As it is working on the eval board properly, I feel drivers are installed properly.

did you copy intrinsics.h at

C:\Program Files\IAR Systems\Embedded Workbench 6.0\arm\inc\c

if not find here attachde the file and copy it to the path above. ________________ Attachments : intrinsics.h : https://st--c.eu10.content.force.com/sfc/dist/version/download/?oid=00Db0000000YtG6&ids=0680X000006I1EC&d=%2Fa%2F0X0000000bk9%2FViVMTNDLjIXBU453RJUQkl1Y0Zi3Z_.btCSQD32eczk&asPdf=false

Add my test program is this

int main() {     unsigned short int a=5;   while(1)   {     a++;     a--;   }   //return 0; }
